Your Jeep is acting up, but for the life of you, you cannot figure out what is going wrong. Your friend is a mechanic, though, and he has a wiTECH system you can use to sort out the problem. The system works with specific vehicles, including Jeep, Chrysler, Dodge, and North American Fiat makes and models. The system offers wireless capabilities that help technicians to narrow down even the trickiest problems. Once they have an understanding what is not working properly, they can apply the appropriate fix, or scan for the next problem. The system works with a computer diagnostic application called StarMobile. The application helps technicians to be even more accurate, since it provides both vehicle data and service information all at the same time within the same interface. If you need either the entire system or accessories that work with the wiTECH system, the vast inventory on eBay ensures that you can find exactly what you need. Once you have the system up and running, you can diagnose any problem in just a few minutes.
